COKE-OVEN DOOR.

' SPECIFICATION forming part of Letters Patent 1\To 725,745, dated'April21, 1903.

Application filed July 9,1902. Serial No. 114,882. (No model.)

To all whom it may concern: 7

Be it known that LEDWIN A. MOORE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, haveinvented certain new and useful Improvements inCoke-Oven Doors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates, primarily, to cokeovens, has especial reference todoors for closing the ovens, and has for its object means for sealingthe doors and dispensing with the use of clay now used for this'purpose;and the invention consists in certain improvements in construction,which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a front elevation showing a door in position on acoke-oven and sealed; Fig. 2, a rear elevation of the door detached;Fig. 3, a vertical longitudinal section on line 3 3, Fig. 2; Fig. 4, afront elevation of a section of the door on an enlarged scale; Fig. 5, atransverse section of the same; Fig. 6, a side view of the brace-barlink-shaft detached; Fig. 7, a like View of the brace-bar hinge-shaft,and Fig. 8 a side and end view of one of the links .or latches detached.

Reference being had to the drawings and the designating charactersthereon, l indicates the oven-door, comprising an outer plate or base 2,having a surrounding right-angled member 3, provided with a face 4:,which engages a seat 5, of asbestos or like material, on the door-frame6. To the base 2 is secured an inwardly-extending section 7, having asurrounding flange 8, by which the section is secured to the base byrivets 9 or bolts.

The door 1 is lined with an insulating material 10-such as asbestos,magnesia, or the like-and over it are laid one or more layers ofrefractory material, such as tiles or firebrick 11, to serve as anon-cond actor of heat a resistance to the deleterious efiects of theheat of the oven on the doorand to refract or turn the heat of the ovenback upon the end of the body of coal in the oven adjacent to the door.This portion of the door being subject to the greatest wear ordeterioration due tojthe high degreeof heat in the oven is renewable byreplacing the burned-out tiles or brick and the asbestos, and when thesec- ,tion 7 yields to the action of the heat it may be renewed byseparating it from the base 2 and replacing it with a new one. The dooris provided with a bail12, by which itis raised after it has beenwithdrawn from the doorframe, and is also provided with an opening 13for the insertionof a leveling-bar. (Not shown.) The door enters anopening 14 in thedoor-frame 6, which door-frameforms subject-matter ofanother application for a patent filed herewith and serially numbered114,884. I

16 16 indicate 'buckstays extending up the front of the coke-oven andare secured to the masonry thereof in any preferred manner, with thebases 17 off-the buckstays resting upon the faces 18 of the-door-framesto hold them in position, and between said buckstays 16 at suitableintervals are secured lugs 19 by bolts 20, passing through the buckstaysand the lugs, and-thelugs areprovided with openings 21 21 to receive ashaft 22, which'forms a hin'ge'for the clamping or brace bars 23,mounted on said shaft on bearings 24:, which are eccentric to the shaft,as shown in the cross-section on linec d, Fig.6. The

function of these eccentric bearings is to force the clamping barsagainst the door of the oven when theshaft 22 ;is revolved by a wrenchengaging the square section 25 on the shaft and to press the dooragainst its seat on the door-frame and prevent'play or lost motionbetween the door and its seat'on the door-frame. The brace-bars-areconnected together near their outer ends by a rod 26, with thimbles ofgas-pipe 27 on the rod interposed between the bars to properly spacethem and form a rigid framework for the brace-bars, and each barisprovided with set-screws 28 28 on opposite sides of the transversecenter of the door for the purpose of lining up or truing the door toits seat on the door-frame to produce an absolutely tight or sealedjoint to prevent the escape of gas or heat from the oven while the coalis being coked, and thus dispense with the clay now used to seal thejoints of coke-oven doors. At the opposite side of the door are lugs 29,

also secured between buckstays 16 by bolts 20, and each lug is providedwith an opening 30 to receive a bolt or rod 31, by which the links orlatches 32 are secured to the lugs by said bolt passing through anopening 33 in each latch, (see Figs. 5 and 8,) and all the links areconnected together by a rod or shaft 34, which is provided with bearings35, also eccentric to the shaft, as shown in cross-section on line efinFig. 7, which shaft engages the ends 36 of the brace-bars 23 and pressesthem toward the door and the door to its seat as the shaft 34: isrevolved in the links by a wrench engaging the squared portion 37 of theshaft 34. The set-screws 28 preferably bear upon bosses 38 on the door,and as the inner or exposed portion of the door becomes burned thesection '7 is removed and a new one supplied, thus leaving the base 2for further use.

The brace-bars 23 being secured together by a rod 26, swing laterally onshaft 22 to clear the opening in the door-frame '6 for the insertion andrenewal of the door, the insertion of a pusher-head at one end of theoven, and the discharge at the opposite end thereof.

The oven having been discharged of its coke, the door 1 is placed inposition in the door-frame, the brace-bars 23 swung into position acrossthe door, the links 32 swung over the ends of the brace-bars, when theshaft 34 is revolved and made to engage with the outer surface of theends 36 of the bracebars, and the door forced to its seat on thedoor-frame andfirmly locked thereto.

Having thus fully described my invention, what I claim is l. A coke-ovendoor consisting of a base, a detachable inner section secured to saidbase, a non-conducting material serving as a doorlining, and aninsulating material between the non-conducting material and said base,both of which materials are within and surrounded by the wall of saidsection.

2. A coke-oven door consisting of a base provided with aninwardly-projecting member having a face for engagement with a seat on adoor-frame, a detachable inner section secured to said base, adoor-lining of nonconducting material, and an insulating material,within and surrounded by the Wall of said section.

'3. A coke-oven door; in combination with a plurality of clamping-barsconnected at both ends and crossing the door, a shaft extending throughthe clamping-bars and having bearings eccentric thereto and on whichbearings said clamping-barsare mounted, and means for engaging the freeends of all of said bars synchronously.

4. A coke-oven door; in combination with a plurality of hingedclamping-bars connected at both ends and crossing the door, movablelinks, and a shaft extending through said links and having bearingseccentric thereto and which bearings engage the free ends of theclamping-bars.

5. A coke-oven door; in combination with a plurality of clamping-barscrossing the door, a shaft having bearin gs eccentric thereto and onwhich the clamping-bars are mounted, movable links, and a shaftextending through the links and havingbearings eccentric thereto whichengage said bars.

6. A coke-oven door; in combination with clamping-bars crossing thedoor, a shaft on which said bars are eccentrically mounted, movablelinks, and a shaft having bearings thereon eccentric thereto, and whichshaft engages the movable links and the free ends of the clamping-bars.

7. A coke-oven door; in combination with a plurality of clamping-bars,movable links, a shaft on which the clamping bars are mounted, and ashaft which passes through the movable links, and means on each of saidshafts for forcing the door to its seat by revolving the shafts.

8. A coke-oven door; in combination with clamping-bars, movablelinks,shafts on which said bars and links are mounted and provided withmeans for forcing the door to its seat by revolving the shaft, andset-screws in the clamping-bars.

9. A coke-oven door; in combination with a plurality of clamping-barscrossing the door, buckstays on the front of the oven, lugs secured tosaid buckstays, a shaft engaging said lugs and on which theclamping-bars are mounted, movable links, buckstays on the opposite sideof the door, lugs secured to said buckstays and a shaft engaging saidlugs and on which said links are mounted,

In testimony whereof I affix my signature in presence of two witnesses.
